6x – 4y = 9
4y = 6x - 9
y = 6/4 x - 9/4
y = 3/2 x - 9/4 this line has slope = 3/2
perpendicular line, slope is opposite and reciprocal so slope of this line = -2/3
answer:
A. y= - 2/3 x - 4 (only this line has slope = -2/3)
Answer:
-2(x²+x-4)
Step-by-step explanation:
(2x)(-x)+8-2x
= -2x(x) + 8 -2x
= -2x² - 2x + 8
= -2(x²+x-4)
Is a measure of the center for a set of numerical data
Answer:
A.
Step-by-step explanation:
<u>Conditional probability</u>:-
If E and F are two events in a sample space S and P( F) ≠ 0 , then the probability of 'F' after the event 'E' has occurred, is called the conditional probability of the event of F given E and is denoted by
P(E/F) =
"Police report that 78% of drivers are given a breath test
36% a blood test and 22% both tests
let 'B' be the event of blood test and 'Br' be the event of breath test
Answer:
3.6 and 8.4
Step-by-step explanation:
you put it into proportions
?/12= 30/100
you do 30 times 12
then divide it by 100
?/12 = 70/100
multiply 70 and 12
then divide it by 100
